BDNF deficiency and enriched environment treatment affect neurotransmitter gene expression differently across ages.

ABSTRACT: Deficiency of activity-induced expression of brain-derived neurotrophic factor (BDNF) disturbs neurotransmitter gene expression. Enriched environment treatment (EET) ameliorates the defects. However, how BDNF deficiency and EET affect the neurotransmitter gene expression differently across ages remains unclear. We addressed this question by determining the neurotransmitter gene expression across three life stages in wild-type and activity-dependent BDNF-deficient (KIV) mice. Mice received 2-months of standard control treatment (SCT) or EET at early-life development (ED: 0-2 months), young adulthood (2-4 months), and old adulthood (12-14 months) (N = 16/group). Half of these mice received additional 1-month SCT to examine persisting EET effects. High-throughput quantitative reverse transcri
